I like iced (well, chilled) coffee, although I will happily drink hot coffee if that’s not available. I also drink tea, and don’t really understand the idea that people should like one or the other, but not both.
I take what I’m given, and don’t ask for one if offered the other. Unless asked by family or a close friend, the answer to ‘I’m making tea, would you like a cup?’ should never be ‘May I have coffee instead?’ or ‘Do you have decaffeinated hibiscus flower tea, please - oh, but only if it’s the one with hints of orange blossom’. The answer is ‘yes please’ or ‘no thank you’. Usually if tea is refused a host will offer coffee if they have some (and have time or inclination to brew it) but I think it’s a bit rude to assume the right to ask. The same applies in reverse, of course. Asking for a glass of water is acceptable, but nothing more (IMO).
Obviously in a cafe people can be as picky as they like, but in someone’s home unless specifically offered ‘tea or coffee’ or ‘a hot drink’ I assume that only what I am offered is easily or conveniently available. It’s a bit like being offered a biscuit and saying, ‘No thanks, but if there’s a bacon sandwich going I’d love one. With brown sauce, please.’
